内容简介：Aviation fuel is a complex mixture with extremely complicated thermal decomposition and combustion reaction pathways. It is difficult to systematically understand the combustion mechanisms of complex kerosene fuels relying solely on current experimental methods and computational techniques. Guessing and providing all possible reaction pathways manually is difficult to achieve, and calculating each reaction pathway using quantum chemistry methods is even more impractical. Driven by the goals of carbon peak and carbon neutrality, people are constantly exploring new low-carbon and zero-carbon fuels, which puts forward a more urgent demand for the efficient construction of high-precision combustion mechanisms. Here we report some recent progress we have made in this direction. By fully integrating machine learning and physical models, we have achieved rapid searching of combustion reaction pathways and fast prediction of rate constants. The introduction of machine learning methods ensures the efficiency of the method, while the physical model fully guarantees its accuracy and extrapolation capability. The development of this method is expected to provide more reliable and efficient tools for the rapid construction of combustion reaction mechanisms.
